Abstract
A kind of novel fabricated combined joint, mainly including fastener, girder steel, steel column, high-strength bolt, pre-buried thin-walled steel plate, built-in fitting, butt weld.First, girder steel and steel column are connected with high-strength bolt by fastener, the turning power of combined joint is improved, so as to causing structure preferably to form pressure arching under Impact Load and playing catenary effect, the shock resistance and progressive collapse-resisting performance of structure is improved.Secondly, the shearing bolt for being embedded in prefabricated board span centre is attached to girder steel and precast slab, improves node shear resistance.Furthermore, the built-in fitting for being embedded in plate two ends can be attached by butt weld so that adjacent two boards are connected, and to the hogging moment of resisting structure seat part, improve the globality of structure.Assembled combined joint of the invention realizes factorial praluction, live quick assembling, it is to avoid scene carries out pouring for concrete, improves efficiency of construction, reduces environmental pollution.
Description
Technical field
The invention belongs to engineering structure technical field, and in particular to a kind of new prefabricated assembled combined joint.
Background technology
Steel has the advantages that bearing capacity is high, rigidity is big and anti-seismic performance is superior with Combined concrete node, therefore in dress
With being widely used in formula structure.And current combining structure is mostly rigidly connected using full welding, not only site operation speed is slow, work
Industry amount is high, environmental pollution serious, weldquality is difficult to control to, and the turning power and Hysteresis Behavior of structure are poor, ductility is low,
Shock resistance is poor.The Semi-Rigid Composite Joints of end-plate bolted connections have more preferable turning power and Hysteresis Behavior, can be in earthquake
Mechanical property more is shown under dynamic or Impact Load, the pressure arching and catenary of combination beam can be effectively played
Effect is so as to there is more preferable progressive collapse-resisting performance, and easy construction is pollution-free.In other combined joint structural system
During concrete slab construction, generally using cast in situs, not only environment is polluted, efficiency of construction it is slow, and difficulty of construction compared with
Greatly, design complicated.Therefore seek that a kind of anti-seismic performance is good, efficiency of construction is high, the novel fabricated of construction material recoverable
Combined joint, the problems demand of the anti-seismic performance and progressive collapse-resisting ability that improve structure is solved.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide the new prefabricated assembled combination section of one kind
The characteristics of point, process is simple, easy construction.
In order to overcome the above-mentioned deficiencies of the prior art, the technical solution adopted by the present invention is：
A kind of new prefabricated assembled combined joint, including fastener, fastener are used to connect girder steel and steel column, and girder steel and steel column are right
Position reserving hole, reserving hole is answered to be used to place high-strength bolt, fixed by nut, precast slab bottom both sides and steel
The pre-buried shearing bolt in position and thin-walled steel plate of beam contact, reserving hole is used to place shearing bolt, precast concrete on girder steel
The pre-buried built-in fitting in plate top both sides, the built-in fitting on adjacent two pieces of precast slabs is welded with butt weld.
Described fastener is formed with welded steel plate by channel-section steel, in its position corresponding with reserving hole on girder steel, steel column
Answer reserving hole.
Described built-in fitting is that have pre-embedded steel slab and embedded ribs to be welded, and integral built-in is on precast slab top two
Side.
Compared with prior art, the beneficial effects of the invention are as follows：
1）The present invention uses prefabricated assembled combined joint, a kind of new prefabricated fastener of invention to connect bean column node, meet design
It is required that, all components are machined in engineering, transport to behind construction site, can assembly connection at the construction field (site), reduce existing
Field welding job improves efficiency of construction.
2）The present invention is attached by the bolt being embedded on concrete slab with girder steel, reduces cast-in-place concrete
And the work of welded steel, easy construction.
3）The present invention can connect two pieces in advance in precast slab outer surface pre-embedded steel slab by welding pre-embedded steel slab
Concrete slab processed resists the hogging moment at bearing, improves the globality of structure.

Specific embodiment
Make narration in detail to the present invention below in conjunction with the accompanying drawings.
As shown in Fig. 1,2,3,4,5, a kind of new prefabricated assembled combined joint, including fastener 1, fastener 1 is used to connect
, in correspondence position reserving hole, reserving hole is used to place high-strength bolt 4, by spiral shell for girder steel 2 and steel column 3, girder steel 2 and steel column 3
Cap 5 is fixed, the bottom both sides of precast slab 6 and the pre-buried shearing bolt 7 in the position that girder steel 2 is contacted and thin-walled steel plate 8, girder steel 2
Upper reserving hole is used to place shearing bolt 7, the pre-buried built-in fitting 9 in the top both sides of precast slab 6, adjacent two pieces of concretes
Built-in fitting 9 on native plate 6 is welded with butt weld 10.
Described fastener 1 is welded with steel plate 14 by channel-section steel 13, corresponding with reserving hole on girder steel 2, steel column 3 at it
Position answer reserving hole.
Described built-in fitting 9 is that have pre-embedded steel slab 11 and embedded ribs 12 to be welded, and integral built-in is in precast slab 6
Top both sides.
When constructing at the construction field (site), after girder steel 2 and steel column 3 are installed, by the shearing bolt 7 of precast slab with
Steel beam flange reserving hole aligns, and is installed in reserving hole, and is fixed with nut, forms an anchorage effect, now
Precast slab is to be installed on girder steel top.After concrete slab integral installation is finished, by phase on two pieces of precast slabs 6
Adjacent built-in fitting 9 is welded together using butt weld 10.
